Fantasy: A Hundred Sons Become Saints, My Family is Invincible

[Fantasy + Aunt Chong + Cao Cao + Thrilling Flight + Banshee + Invincible]

Lin Changqing transmigrated to a world where martial arts reign supreme and became the only legitimate son of the Lin family.

Unfortunately, not only was his martial arts aptitude extremely poor, but he was also born impotent.

After his adoptive father passed away, the question of how to continue the family line became his concern.

Fortunately, the system arrived.

You can receive a reward simply by getting married and having children.

Lifespan and physical condition can both be improved.

Furthermore, as the system upgrades, he can also gain a portion of his offspring's cultivation.

In that case, what else is there to say but get married and have kids!

As time went by, one day Lin Changqing discovered that all the myriad worlds now belonged to the Lin family!
